, i invention isa tobacco pipe of a type adapted to cool the smoke, provide a charn-` `ber Yfor nicotine and tobacco juioesfandV a 1 catch chamber' for saliva'. Y 5 An object of my invention is in a' tobacco' .pipe to' construct a passage arranged'y in zig pzags, whereby thesinoke is required to travf erse" a considerable distaneefrom the bowl of the pipe to themouth, thereby `cooling' the l0 smoke. A Specific obj ect of thie 4featureis' to 'utilize a' removable plug hevingrzig zag or other passages 'on its periphery adapted to forni a continuous extended passage for the K ,p l y e* n i f 1s a! plany viewjofthepipe Showing srnokepassages by afhorifi smolieand thereby cool the smoke.

and that the lug 14 prevents tov afcertainjex# tent saliva being drawn upwardly.

In the construction shown in Fig. 9, indi# cating a plug alternative to the plug 8, this., type ot plug instead of having longitudinal grooves connected by curved .ends has a con-v tinuous helical groove 20, one end 21being adapted to register with the smoke passage 12 and t-he other, end 22 with the notch' 117 It is to benoted that both of these plugs have a center opening 23 whiclris made merely for sake of lightness. v.l-lowever, it desired smallbore holes 2e may be made from the grooves occupying an upper positionin the plug when it is'inserted, tothe hollow space 23 to catch any tobacco juices orgsuch'like that may be drawn into the said grooves? As in this type of pipe having a long passage for the smoke, tobacco and juiceand moisture are apt to plug the grooves, these outlets allow such juices to collect intothis hollow space in the plug and befreadily cleaned; out. lt, is believed that Athe manner of usage of my'pipe is obvious, however, it may be stated that the smoke is draw-n directly downwardly struction or specific features of my invention into the nicotine chamber inthe socket and from thence through. the passage 12, the zig Zag grooves or helicalggrooves in the, plug to the notchl? and thence through the smoke duct to the mouth. Thefpipe Vis readilyV cleaned as the base plug 3 may be removed in a simple manner. The mouth piece may also bc detached and the plug 8 drawn out ot the chamber containingsame. f Y 'i Y' lt will be apparent that the general conmay be changed to adapt same to different types of pipesV and to :different shapes thereof, such as curved-pipes or the like and that such changes will be withinthe spirit of'my Iinvention as set forth in the description, drawings and claims;v For instance, itwwould be v,an

`obvious modification of my inventiontoform the smoke groovesf'in the body ,of the pi e,

suchavstorming grooves in the v stem and t-4 ting a lplug thereinvto formv continuous zig zag passages. i

It willbe .notedthat a characteristicof my invention is Vthatthe `plug inthe pipe has' a hollow space withsmall apertures `connecting to the direct smoke passage, so .thatnicofV tine juices from the tobaccov may `fall through these apertures into the hollow space, but the smoke. itself will not traversethisfspace, as it is in eect a dead air chamber.4 This chamber has no through passage by which smoke may travel from the bowl to the mouthpiece. Therefore, as the nicotine and other tobaccol j raices are carried by the smoke, they will be collected in the smoke passage and low into this hollow space. Manitestly, as such space becomes filled, the airwill become displaced; but it isinot intended, and the con-` struction does not allow, the smoke to pass through this hollow space, YHaving 'describe-d my invention, what I claimb is *11A pipe comprising in combination, a structurejliaving, awbowl and an integrally tormedsocket in'ali'gnment, separated by the base of thebowl, there being smoke vents from the bowl intolthe socket, a base plug screwed Ainto the socket, ,a stem formed infY tegral with the structure having the bowland the socket, .the stem havinga chamber, a removable plug. inserted in said chamber, with its end abutting againstthefw'all structure of the socket, Ytherefbeing a smoke passage from lthe socket tothe chamber of the stem, the plug having grooves forming a smoke assao'e and a mouth iece with a smoke'duct i ,D 7 v e j connected tothe end ofthe stem;v y
